Horse owners often associate electrolyte supplementation with warm weather, however, this actually has nothing to do with seasons. The provision of electrolytes depends entirely on the amount of work and sweat loss taking place, so for certain horses supplementation is important every season.

One of the most significant effects it can have on a horse is exerting too much pressure on its back muscles. This will cause an improper flow of blood to the muscle and cause pain. No muscle can develop and work properly without an adequate blood supply. Over time, that muscle will degenerate or atrophy.
